The gene that codes for one component of this protein is contained in the short arm of chromosome 5, which is deleted in cri du chat syndrome, and that gene's loss of function may contribute to that condition. Inhibitors of this enzyme may be of limited efficacy in treating a certain disease due to the existence of the ALT pathway. Scott Cohen discovered that this enzyme contains two molecules of dyskerin. This enzyme is named for the (*) repeats of TTAGGG that it adds to the 3' end of chromosomes. For 10 points, name this enzyme discovered by

For 10 points, name this enzyme discovered by Carol Greider and Elizabeth Blackburn, that compensates for the continual shortening with each replication of its namesake aging structure.
